The secret service has also been accused of issuing misleading statements regarding an incident involving an intruder who jumped a fence and entered the White House carrying a knife.

The secret service agency is overseen by the Department of Homeland Security.

Homeland Security secretary, Jeh Johnson is quoted in the report as stating of Pierson’s resignation, “Today Julia Pierson, the director of the United States secret service, offered her resignation, and I accepted it. I salute her 30 years of distinguished service to the secret service and the nation.”
